The more I experiment with Jewelry Clay the more I love it!
This is a little inspiration to consider rubber stamping your clay. All I did was place some clay in a bezel, stamp my Frida image with black Staz-on and add some crystals to the edges. When the clay was cured I coloured it with metallic pastes.
My step by step rubber stamping demo is a good one to review and I have linked it here.
